Unity and Oculus Deep Link integration

Hi Devs,

I am using Unity 2021.3.16f1

So my question is : I am using unity and developing an application for oculus quest 2. In my scene I have 2 buttons and each has a link to open. now the thing is that link is of Spatial.io environment and i already have spatial.io application installed in Oculus, What i want is When i click the button for spatial link that should open in Spatial.io application. Guide me to integrate this deep link feature. I have already checked documentation for Oculus the process that they have mentioned is for OVR Not for XR.
I any one has any solution regarding this please do the needful.
Thank you.
